| Abstract | A laser driving integrated circuit ( 8 ) to drive a laser element is mounted in an optical housing, and a wiring pattern of an actuator line ( 6 ) for supplying an actuator ( 1 ) with drive signals to drive the actuator ( 1 ) through a relay circuit board and a wiring pattern of a laser drive line ( 5 ) for supplying drive signals from the laser driving integrated circuit ( 8 ) to the laser element are formed on the same flexible wiring board ( 4 ), and, when the flexible wiring board ( 4 ) is folded, a shielding part ( 7 ) connected to the ground line is arranged to intervene between the overlapping wiring patterns of the actuator line ( 6 ) and the laser drive line ( 5 ) of the flexible wiring board ( 4 ). |
